THE ANS SHOULD BE D 8TH ONE see this sum can be done by eliminatin options. check the continuity at x=2 which shows it actually is continous so the function is continous in the entire range given. now if you draw a rough graph of the equation given to you will see that the fuction is decreasin in [-1,2] and hence the only option left is d and it is obvious to as the second function can have a maximum value only at x=2 and so is it with the first function to draw a very rough fig of the graph you should know that graphs look like smooth v ansd intersect at x axis and the points which form the equations roots which can be calculated with ease please correct me if i am wrong or nudge me if you have any doubts
